This transducer will work with almost any of the Garmin's Echomaps, GPSmaps and Striker.
Will work with either 4 pin or 8 pin as an adapter comes with it. If you need it for 12 pin model . Have extra adapter for that but it is not included .
It will work with the non-chirp Echomaps as a standard frequency transducer. It just won't be able to use Chirp function.
I have upgraded to the PS 22 Panoptix and no longer have need of this. PM me for phone number if interested.
Comes with float for ducer if you want or need .
